Edit: Wow, I didn't need any of these; Meld via Nemo Compare does the trick in conjunction with the built-in text editor, Xed! Glad I came across this delightful plugin!
~~Kate~~. ~~Zed~~. ~~Basically anything with Git's diff doesn't seem to allow live edits to either file directly in the comparison itself; I have to open one of the files in another text editor and search for the discrepant lines manually. Is there anything that can rival VSCodium out there (which, yes, has no telemetry but still feels too resource-heavy relative to the Syncthing sync-conflicts for which I intermittently use it to manually resolve)?~~
~~The search has gotten so bad that it feels like a failure to have to download Notepad++ on Windows to try to run it through Bottles, in which I then had a graphical scaling error (had to restart with 200% DPI, but the mouse cursor is still tiny) and I couldn't open my own Linux user directory in its file browser.~~
~~I'm pulling my hair out; I had no idea that this would be such a ridiculously difficult search. I'm trying NeoVim next, with possibly LazyVim, but I fear the same outcome...~~
If you're comfortable with vim,
vimdiffis lightweight, works well for simple stuff, and you probably have it installed already (can usevim -dif not)I absolutely could not wrap my head around even gvim, but thanks for the idea; I know it's well regarded, but my skull is too thick. The Nemo Compare plugin apparently works flawlessly!
